Calvert, the son of a quondam London brewer who died worth £30,000, received a salary of £1,130 per annum as secretary to the lord chamberlain. In 1820 he came forward again for Huntingdon on the interest of the Dowager Lady Sandwich. He was inaudible on the hustings but was returned after a token contest. Samuel Wells, the local radical challenger, denigrated him as a sinecurist who could well afford to buy his seat: he was the lord chamberlain’s lackey and ‘pops up his head, like Punch in a puppet show’.
Calvert voted with government against tax reductions, 3, 18 Mar., and military economies, 10 Mar. 1823. He divided against repeal of the Foreign Enlistment Act, 16 Apr., inquiry into the prosecution of the Dublin Orange rioters, 22 Apr., reform of the Scottish electoral system, 2 June, and inquiry into chancery delays, 5 June. Either he or his cousin Nicolson Calvert intervened in committee, 7 May, over absolving witnesses from their oaths as jurymen. He divided for the usury laws repeal bill, 17, 27 June 1823. He voted against reform of Edinburgh’s representation, 26 Feb. 1824. He was credited with an unlikely vote in the minority for repeal of the window tax, 2 Mar. He divided against the abolition of flogging in the army, 5 Mar., and for the usury laws repeal bill, 8 Apr. He voted in defence of the conviction of the Methodist missionary John Smith for inciting rebellion among the slaves in Demerara, 11 June, for the Irish insurrection bill, 14 June 1824, and the Irish unlawful societies bill, 25 Feb. 1825. On 15 Apr. he was one of the Members unable to hear the Speaker put the question on the Southwark paving bill, and subsequently voted to postpone it. He voted for the duke of Cumberland’s grant, 30 May, 2, 6, 10 June 1825. He voted with government on the Jamaican slave trials, 2 Mar., the ministerial salary of the president of the board of trade, 10 Apr., and against reform of Edinburgh’s representation, 13 Apr. 1826. The Huntingdon Gazette, outraged at his conduct, denounced him as a ‘well-trained beagle’ who always ‘hunted with the treasury pack’.
Calvert was re-elected unopposed in 1826, when he justified his opposition to Catholic relief on the ground that history proved it dangerous to ‘put civil power in their hands’. He said that he would always oppose parliamentary reform and declared it preferable to keep the ‘practical good’ of the present system than to encourage the ‘delusive speculations of theorists’. As to the corn laws, experience had shown that controlled admission was more beneficial than total prohibition; but if any doubts arose, he would ‘give the bias in favour of agriculture’.
Calvert stood again for Huntingdon in 1830 and was returned after a nominal contest. He refused to be drawn over his future conduct in the House.
